Mettag: RED – Priority I – Immediate attention. Identifier is a Mettag torn to the red stripe or Roman numeral I placed on the forehead or back of left hand. First priority casualties are those that have life-threatening injuries that are readily correctable. For purposes of priority for dispatch to the hospital, however, a second sorting or review may be necessary so only those “transportable” cases are taken early. Some will require extensive stabilization at the scene before transport may be safely undertaken. A red tag may be used as an additional means of identification.
